next in thread | raw e-mail | index | archive | help
Hi,
I don't have alot of information to provide yet on
this yet. The fault information scrolls off the top of the
console...
I have /usr/obj mounted on a ccd. Less then 2 minutes
into a make world, the console shows a ccd problem, error 5.
Page fault in the kernel.
The above problem is repeatable (but the machine is not
infront of me right now).
I unmounted the /usr/obj ccd filesystem, and am running
a make world onto the /usr system which is not a ccd and
things seem to work fine (so far).
It may be monday before I can get a kernel rebuilt with
the debugger enabled.
This is a single processor machine, UP kernel, sources
current as of 11:30am EST. No error information is written
to syslog.
-John
